c# - 中等信任下的 ODP.net 访问违规

转载作者：太空狗更新时间：2023-10-29 23:09:57

环境:

Windows Server 2008 R2
IIS 7.5
.NET 4.0, Integrated Application Pool
Oracle Client 11.2.0.2.0
ODP.net 11.2.0.2.3

我有一个网站使用 ODP.net 连接到我们的 Oracle 数据库，在“完全信任”下，该应用程序运行完美。但是，当我将应用程序更改为使用“中等信任”时，我开始从应用程序中获取不一致的 NullReferenceExceptions。大部分时间代码都有效，但每 10 个请求左右我就会收到 NullReferenceException。查看事件日志后，我发现 NullRefernceException 通常对应于 w3wp.exe 崩溃。

Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2
Faulting module name: OraOps11w.dll, version: 2.112.2.0, time stamp: 0x4cea1904
Exception code: 0xc0000005
Fault offset: 0x0000000000024d56
Faulting process id: 0x3ba4
Faulting application start time: 0x01ccdf556d68384a
Faulting application path: c:\windows\system32\inetsrv\w3wp.exe
Faulting module path: C:\Oracle64\product\11.2.0\client\bin\OraOps11w.dll1

显然问题出在 ODP.NET，但为什么它会在“中等信任”中崩溃 w3wp.exe。因此，为了确保我的代码没有做错什么，我编写了最简单的 ASP.NET Web 应用程序:

protected void Page_Load(object sender, EventArgs e) {
    using(OracleConnection conn = new OracleConnection(GetMyConnectionString())){
        using (OracleCommand cmd = new OracleCommand("select localtimestamp from dual", conn)) {
            conn.Open();
            this.aLiteral.Text = ((DateTime)cmd.ExecuteScalar()).ToLongDateString();
        }            
    }
}

在“完全信任”下，应用程序运行良好。在“中等信任”下，该应用程序似乎运行良好，但当我将 IIS 调试诊断工具连接到该应用程序的应用程序池时，该应用程序抛出了数千个这样的错误:

我按照 ODP.NET 自述文件中的说明将 OraclePermission 添加到 web_mediumtrust.config(32 位和 64 位)，但我仍然遇到相同的错误。

关于如何让 ODP.NET 与“中等信任”一起正常工作的任何想法？

最佳答案

从错误消息来看，我相信这里发生的事情是在应用程序运行时，ODP.net 库在某个时候在单独的线程上生成 OracleTuningAgent。当 OracleTuningAgent 正在执行时，它会调用:

System.Diagnostics.Process.GetCurrentProcess()

调用 GetCurrentProcess requires Full Trust ，当您在中等信任下运行时会导致 SecurityException。由于异常没有发生在请求线程上并且未被处理，it causes the web application to recycle (见风险 #1)。

为了确定，我创建了一个测试 Web 应用程序并将其设置为中等信任度。然后我尝试调用 System.Diagnostics.Process.GetCurrentProcess()，但出现以下异常:

Security Exception

The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request failed.

我也尝试了 High Trust 并得到了相同的结果。在 Full Trust 下运行，我的测试应用运行良好。

所以要回答所问的问题，似乎 ODP.net 导致 w3wp 在中等信任下崩溃，因为对 Process.GetCurrentProcess() 的调用需要完全信任。如果有某种方式，您可能能够让您的代码在 Medium Trust 下工作:

配置 .NET，以便对 Process.GetCurrentProcess() 的调用可以在 Medium Trust 下工作
(我试过但想不出办法，但这肯定不行'不是说不可能)，或者
关闭ODP.net中的OracleTuningAgent
